Company History

The company was founded in 1976 by Bill Loonstyn Sr. Starting as a small family operation, it grew by focusing on quality work and honest service. Bill retired in the early 2000s, passing the business to his son, Joe Loonstyn. Many family members and long-time friends have worked here over the decades, building a team with immense hands-on experience. Today, FM & Loonstyn Roofing is large enough to handle big projects but still small enough that the owners personally oversee each job.

Leadership

Owner Joseph Loonstyn has over 30 years in the roofing industry. He started as a helper, moved up to foreman and manager, and now leads the company. Joe’s cousin, Frank McMonagle, who also began as a helper, manages day-to-day operations. Their deep roots in the community and hands-on approach mean they’re not just business owners—they’re craftsmen who understand the work from the ground up.
